Electricity produced on rubbing is

Options

A. static electricity
B. electromagnetic
C. current electricity
D. none of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Concept**: When two different materials are rubbed against each other, they can transfer electrons from one material to another. This transfer of electrons results in one material becoming positively charged and the other becoming negatively charged.

2. **Example of Rubbing Materials**: A common example is rubbing glass with silk. When glass is rubbed with silk, electrons move from the glass to the silk. As a result, the glass becomes positively charged (due to the loss of electrons), and the silk becomes negatively charged (due to the gain of electrons).

3. **Definition of the Phenomenon**: The electricity produced by this process of rubbing two materials together is known as "static electricity." This is because the charges remain stationary on the surfaces of the materials until they are discharged.

4. **Conclusion**: Therefore, the electricity produced by rubbing two materials together is referred to as static electricity.

**Final Answer**: The electricity produced on rubbing is **static electricity**.
